As requested by several people, here are a few shots of the new 5mm 'ultra glass' cubes available from Pets at Home. These are of the 27L version (30x30x30, £39), there is also a 15L version (£29).
Silicon is minimal to the point of almost invisible on the side panels, thicker and less neat at the base but would be hidden by substrate. It has a slight green tinge at the joins but otherwise seems very clear. I've never owned an opti-white tank so I really couldn't compare, but it looks good to me.
Light looks nice (11w), filter looks a bit naff but has a spray bar and speed adjustment. Both work very well, the filter actually seems to provide pretty good flow if you can live with its looks, and the light is a nice clean white colour. Both are night on silent. No heater supplied, but tank does come with a thin mat to sit it on and a glass cover. The little clip-on corner braces that hold the cover glass slide off easily and I doubt they do anything structural, so could easily remove if you wanted it open-top.
